GEORGE M. BEARD, OF ANGOLA, INDIANA.

WINDMILL.

SPECIFICATION forming" part of Letters Patent No. 233,134, dated October 12, 1880.

Application filed August 7, 1880.

To all whom it may concern:

Be it known that I, GEORGE M. BEARD, of Angola, in the county of Steuben and State of Indiana, have invented certain new and useful Improvements in Windmills; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part. of this specification.

My invention relates to an improvement in windmills; and it consists in attaching a collar having two stops formed upon it to the upper portion of the pipe or tube upon which the operating parts of the mill are supported, and which stops limit the movement of the frame in which the wheelis journaled when the wheel is moved in and out of the wind.

It further consists in forming a guidefor the pitman-rod and a guide for a pump-rod in the same piece, the guides for the pump-rod being made adjustable, so that all wear can be taken up, and thus prevent any unnecessary noise.

The object of my invention is to provide a selfregulating wind-wheel which will automatically regulate itself according to the force of the wind, and which shall be cheap, simple, and eflicient in operation.

Figure 1 is a side elevation of my invention. Fig. 2 is a horizontal section taken through the tower, so as to show the centering device. Fig. 3 is adetail planview, showing the guides through which the pitman-rod passes. Fig. 4 is a plan view of the collar which passes over the top of the tube upon which the operating parts of the mill are supported. Fig. 5 is a vertical section taken through the tube and the parts which rest thereon.

Arepresents the tower, which is constructed in any suitable manner, and B is the tube upon which the operating parts of the mill are secured, and with which they turn freely around upon the tower. Upon the top of the tower is formed a recessed flange, G, in which a corresponding enlargement which is formed upon the collar which is passed over the top of the tube B fits, for the purpose of holding the tube in position. At any suitable distance below the top of the tower is secured, by means of set-screws D, the perforated plate E, through (No model.\

which the lower end of the tube B passes, and by means of which the lower end of the tube is centercdin position. This plate or centering device has the set-screws passed through the side braces of the tower into its sides, by means of which screws the plates can be adjusted into any desired position. Should the tower at any time become sprung or inclined to one side, the tube can be straightened into a vertical position by moving this centering device from one side to the other, as may be necessary.

The tube B is perfectly plain from top to bottom, and has passed over and secured to it in any suitable manner the collar G, which has the support H for the vane formed with it in a single piece. This collar has the flange formed upon its lower edge, and which flange fits in the recessed flange O, for the purpose of centering the upper portion of the tube B. Also, passed down over the top of the tube B, and resting upon the collar, is the frame I, in which the wheel is jonrnaled. This frame I has two collars formed upon it, both of which fit over the top of the tube B and turn freely around it when the wheel is being moved in and out of the wind. Between these two collars which are formed on the frame I is a separate and distinct collar, J, which is passed over the top of the tube B, and which collar J is secured rigidly to the tube by means of a set-screw or other suitable device, so that it cannot moveupon the tube B. Projecting outward upon nearly opposite sides of this collar J are the two stops L, which serve to limit the motion of the frame I around the upper end of the tube B. While the collar J is rigidly secured to the tube the frame I can move around the tube the distance between these two stops. One of these stops serves to stop the wheel in the face of the wind, and the other one serves to stop the wheel after it has been moved far enough around to present only its edge to the wind. This frame I, which has the Wheel journaled upon it, is connected by means of a rod, N, with the weighted lever O, and which weighted lever serves to keep the face of the wheel to the wind until the pressure of the wind becomes sufficiently strong to overbalance the weight, when the wheel turns more or less of its edge to the wind. As soon as the wind has subsided the weight forces the wheel back into position again. Also, projecting from the collar J is a flange, I, which projects between the two ears Q, formed upon the support for the vane, and through the two cars and flange is passed asuitable bolt, which secures the collar and the support rigidly together. It will be seen, then, that this collar serves not only to regulate the distance thatthe wheel shall move but also to assist in securing the support ll in position.

Upon the rear end of the box or hearing R, in which the shaft of the wind-wheel turns, is secured the guide S, which extends upward a suitable distance, and has the pitman rod passed through it. Upon the rear side of this guide are secured, by means of set-screws, two slotted pieces, '1, which have their inner ends cut away, as shown, and which have suitable slots made through them, so that they can be adjusted back and forth. These two pieces T form a box or guide for the pump-rod U, and by being made adjustable all wear can be taken up, and thus all rattling and unnecessary noise be prevented. This pump-rod extends a suitable distance up above the box or guide, and has a U-shaped piece either secured to or cast with it upon its upper end, and to which U-shaped piece the upper end of the pitman-rod is connected.

Having thus described my invention, 1 claim- 1. The combination of the tube B, collar J, provided with the two stops L, and the flange P, with the wheel-frame I and the vane-support H, the collar J being made to both limit the movement of the frame and. support the part H, substantially as described.

2. The combination of the guide S, having an opening through its upper end for the pitinan-rod, and the pieces T secured to its rear side, so as to form a guide for the pump-rod, substantially as specified.

In testimony that 1 claim the foregoing I have hereunto set my hand this 13th day of July, 1880.

GEORGE M. BEARD.
